I dont know how you played in the other rounds but i would suggest perhaps quiet early on, see how loose other players are and make the odd move when in the right position.
Just the general tourney suggestion i know but after all you made it this far why do you want to change now?
Just keep an eye out early on for people trying to stack build quickly - do you want to bustout early or try to be there at the end ?
Looks like i'm goin to have to start playing these. Seems like there will be alot of CC regulars in the big one. When people qualify we should start a thread to see who's in.
